IMPROVEM ENT IN SASH-KFASTENERS.

Specification forming part of Letters Patent No. 212,354, dated February 18, 1879; application tiled August 9, 1877.

To all whom it Imay concer-n.'

Be it known that I, GEORGE W. CARY, of Providence, in the county of Providence and State of YRhode Island, have invented a new and useful Improvement in Window-Springs, which improvement is fully set forth in the following specification, reference being had to the accompanying drawing.

The object of my invention is to produce a novel device for holding the sliding sash of' a window at any desired height when the window is opened, and also form a lock to pre vent the window from being opened from the outside after being closed, all as hereinafter fully described and claimed.

The ligure represents a sliding sash in a window-frame.

A represents the sash with my device inserted for use. a is an eccentric-cam, toot-hed `o`n the side that comes in contact with the window-trame. The dotted curved line represents a steel spring, to which the lever c is rigidly attached. 'lhc cam and spring are held in a light metallic frame by means of two pins, b and d. The metallic frame is inserted into the side of the sash with lever c, passing through a small mortise, all being held in the sash by means of two small wood-screws, ce.

The cam a is provided with two lips on the lower side, 'L' and o. The spring to which the lever c is rigidly attached passes under the lip i, for the purpose of actuating the cam. The lip 0 serves as a lock, to lock the sash down by hooking under the metallic piece il, which is inserted and rigidly attached to the Windowframe by means of awood-screw or its equivalent. The spring serves to turn the cam out, so as to engage with the window-frame and hold the sash at any desired height.

By raising the lever c the cam a is turned inward, and the sash can be moved up or down; but when the hand is removed from the lever c the spring throws the cam outward, and the toothed surface of the cam catches on the window-frame very readily, thus making a safe and cheap device for the purpose.

What I claim as my invention, and desire to secure by Letters Patent, is-

rlhe toothed and hooked cam a, in combination with the lever c, rigidly attached to the spring and actuating it, substantially as shown and described, for the purpose set forth.
